What's better than a day spent hiking in a national park? Doing it for free. To celebrate National Park Week, the National Park Service will waive entrance fees to all sites for nine days, from April 16-24, this month.
The NPS plans to skip admission costs for 16 days this year, up from just nine in 2015. Besides National Park Week, free days include the agency's 100th birthday weekend from August 25 to 28 and Veteran's Day on November 11. Campsites and backcountry permits aren't included in the celebration, so while visitors can expect to save between $3 and $30 on admission, they'll still have to shell out for extras.
